Description Anten Skrabec 2022-12-19 19:06:10 UTC 
Heap memory leak in tslib 1.22 allows context-dependent attackers to leak heap chunk address via deleting tslib configuration file

If the /usr/local/etc/ts.conf configuration file does not exist, a UAF vulnerability can occur and the library heap memory address can be leaked.
